Ubuntu 16.04 Sinal WiFi Fraco após inicialização dupla Ralink Rt3290

Question

Eu sou novo no Ubuntu. Nos últimos 3 dias completos, tenho procurado uma solução para este problema sem sorte. Eu li quase toda a questão semelhante postada no Ask Ubuntu, mas não há solução. Poucas pessoas marcam a pergunta como Duplicada. Em vez de marcá-lo como duplicado e redirecionando para outro link alguém pode por favor responder a pergunta aqui.

O sinal de Wi-Fi fraco, tem que ficar muito perto do roteador para funcionar (3-4 pés). Eu tenho janela inicializada dupla e instalei o Ubuntu 16.04 LTS

Controlador de rede: Ralink corp. RT3290 Sem fio 802.11n 1T / 1R PCIe

Neste Ask Ubuntu Pergunta , foi escrito para adicionar a saída destes comandos:

1. sudo lshw -rede rede
2. lsusb
3. lspci
4. dmesg

5. dmesg | grep -i firmware

   Então, estou adicionando-as aqui.

4. dmesg A saída desse comando era muito longa, então eu tive que carregá-lo aqui no Google Drive
